On the connection between mode II and mode III effective thresholds in metals
(Italian Group of Fracture, 2017-07-01)Closure-free long cracks under the remote mode III loading grow in a more complicated way than those under the remote mode II. For bcc metals, a coplanar in-plane spreading of tongues driven by the local mode II loading ... -
Simple criterion for predicting fatigue life under combined bending and torsion loading
(Gruppo Italiano Frattura, 2017-07-01)Multiaxial fatigue is a challenging problem and, consequently, a number of methods has been developed to aid in design of components and assemblies. Following the complexity of the problem, these approaches are often ... -
Strength and Brittleness of Interfaces in Fe-Al Superalloy Nanocomposites under Multiaxial Loading: An ab initio and Atomistic Study
(MDPI, 2018-10-24)We present an ab initio and atomistic study of the stress-strain response and elastic stability of the ordered Fe3Al compound with the D03 structure and a disordered Fe-Al solid solution with 18.75 at.% Al as well as of a ... -
Stress coupling effect on ideal shear strength: tungsten as a case study
(Hindawi, 2016-12-05)Mechanical response of a perfect bcc tungsten crystal to a multiaxial loading was investigated from first principles. The multiaxial stress state consisted of the shear stress and a superimposed compressive triaxial stress ...
